LTE Tutorial (Part 3) LTE MIB and SIBs

[@muhammadhamza-co4cp]

Thank you so very much for all of your lectures. The way of your teaching is simply awesome !!!

[@youssefsabbagh4341]

Great video's !! Please keep uploading on different 5G topics.

Thank you for your all efforts, I learned a lot!

Thanks Arash for your feedback.

Explaining very clearly and easily understand way. Thank you

Very nice explanation, helped me a lot! Thanks!

Nice explaination ..keep it up ... Thanks a lot

Why not MIB broadcast through DL SCH & PDSCH?

[@abdulrahmanalmeqdad8111]

in minute 08:27: You said QRXLEVMIN which is minimum RSRP required?! please confirm it is RSRP or RSRQ?

[@puliraju9222]

I have one doubt. In SIB3 Already we have information about all neighbour cell information of intra,inter,inter-RAT .then why need to SIB4,SIB5,SIB6,7,8.....?

[@muhammadhamza-co4cp]

I've a question. I understand that TTI of SIB1 is 80ms. SIB1 is transmitted over 5th sub-frame and rest 3 others SIB1 are re-transmitted within the time duration of 80ms & has a gap of 10ms right? also rest of the others SIB's (2, 3, etc) periodicity is based on SIB1 right? So my query is how can we calculate the periodicity of other SIB's with respect to SIB1. I would really appreciate it if you could upload a lecture on this one as well. Moreover, First SIB1 is transmitted when Mod 8=0 and rest 3 others SIB1 are re-transmitted when Mod 2=0. What are these mod 8=0, mod 2=0? how do we calculate these things? Thanks

[@muhammadhamza-co4cp]

I'm looking for a detailed explanation on this concern. Thank you !!

[@kathirvelp4326]

Can you plz explain, how SIB3, SIB4, SIB5 TTI Sub frame diagram will come?

[@lteplusplus1225]

Their periodicity is present in sib1. Suppose periodicity of sib5 is rf5 (5 radio frames) then after every 50 ms sib5 will be triggered (note 1 radio frame is of 10 ms)

[@kathirvelp4326]

@@lteplusplus1225 you mean, all the SiB2, sib3, . . . sib 11 TTI info presented in SIB1 right?

[@lteplusplus1225]

@@kathirvelp4326 yes...in other words You can say at which tti the particular sib will be triggered.... That info is provided by sib1.

@@lteplusplus1225 in wat subframe no sib 5 will be scheduled in the above case?can u please explain

[@pawansingh-ub2ej]

Is inter lte frequency inter band?

[@Amirscert]

Hi, As you mentioned SIB is transmitting over BCCH then DL-SCH then PDSCH. But i have a query how PDSCH comes into picture before RRC connection and who will decode this PDSCH and for which information?

[@lteplusplus1225]

Hi Amir....PDCCH carry RNTIs like: SI-RNTI if PDSCH is carrying System Information. RA-RNTI if PDSCH is carrying Random Access related information. P-RNTI if PDSCH is carrying paging related information. C-RNTI if PDSCH is carrying real time traffic. So, its PDCCH which tells UE that what information is present in PDSCH whether it is related to System Information, Random Access, Paging and Real time traffic. Thats why PDCCH i spresent in each and every Subframe.

[@r.dineshkumar3984]

UE decode this information

[@zafarhusain1920]

Ue decode pss,sss,rs we get pci then with the help of pci we found rs location in resource grid after finding location we get rs power with the help of rs power we decode PBCH and get MIB(DL BW, PHICH,SFN) then we decode PCFICH with the help of rs power we get CFI(1,2,3) length then we get PDCCH length then we get PDSCH it gives SIB1 info then PDCCH+PDSCH we get SIB2.

[@varun284]

Get you concept clear...Thanks

[@sivakumarverrigukka7872]

Why mib and sibs are transmitted on different channels

[@abdulrahmanalmeqdad8111]

From minute 06:07 to 09:46: You were explaining SIB 1 or what?

[@abdulrahmanalmeqdad8111]

Thanks for the video

[@vikasraj49]

How SIB is Decoded by UE?

[@lteplusplus1225]

sib1 carry the indormation of other sibs like repetetion period in terms of radio frame so ue come to know at which subrame partucular sib will come and ue decode sib easily.

[@engineersride8273]

nice explaination , but you have used "Subframe" in many places which ideally should be Frames.
